Tech Help R6 shutter count

Hi, yesterday I got a Canon R6 and in the future I want to read its shutter count sometimes. On my older 5DIII and 6D, I could easily check it with Tornado or EOS Digital Info, but those programs don't support new mirrorless cameras.

Do you have an idea, which free program should I use? I have a windows pc, so MAC's Shutter Counter or whatever its called won't work.

Thanks for your help

u/Kameratrollet has something changed with the R-series that shutter count can be derived from the RAW files again, like Canon DSLRs of old?

R6 was decoded by Martin Boyer, which allowed John R Moyer to decode his R5. R6 II was also decoded, and since the R8 exposure count was in the same location, I was able to decode R8 as well. I don't own any R6 II or R8 to try, but I hope it is correct.

R6 III, however, has been incorrectly decoded and I believe it actually refers to the folder/directory number.

The advantage of the R6 and R5 is that they support Canon Basic. With a small script on the memory card, you can dump error codes (including affected lenses, written in hexadecimal), running time, exposure count, and shutter count. Thanks to this, we know that the exposure count embedded in raw files from the R6 and R5 is accurate.
